A discussion is presented on the problems encountered in preparing andor obtaining pure anhydrous nickel fluoride. To date, the purest material obtained is 98.5 NiF2. Iron, nickel oxide and free HF are the usual contaminants. Positive electrode fabrication techniques are discussed. It has been found necessary to increase the binder to 10 when high surface are carbons are used as conductive diluents. Two binders, Foundrez 92-080 and Microthene FN500 are used. Voltammetry sweeps were used to evaluate GBL and PC with KPF6. Previously, electrolyte studies had indicated that GBL had less ion-pairing than PC both with KPF6 but there was no appreciable difference in voltammetry sweeps using the two electrolytes. Author
